IMPROVEMENT IN ELECTROPLATlNG-FRAMES,

Specification forming part of Letters Patent No. 197,408, dated November20,1877 application filed August 30, 1877.

To all whom it may concern:

Be it known that I, JULIUS W. ROGERS, of West Meriden, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inElectroplating-Frames tion of the same, and which said drawingsconstitute part of this specification, and represent, in-

Figure 1, perspective view 5 Fig. 2, end view, sectional. I

This invention relates to a device for holding articles to beelectroplated, commonly called plating-frame, and with special referenceto plating articles in which only part of the article is to be coated,such as screwheads, knobs, and the like; the object being to make theframe adjustable relative to the surface of the bath, so that only thearticle, or that portion of it to be plated, will be immersed; and itconsists, substantially, in a frame attached to the pole by ascrew-hook, the said hook adjustable in the frame, and combined with aset-nut to hold the frame when properly adjusted, and in details ofconstruction, as hereinafter described, and more particularly recited inthe claims.

Inillustrating the invention, a frame for plating ornamental heads isshown. This is composed of several parallel bars, A, 'connected togetherby diagonal bars 13, pivoted to each of the bars A, so that the bars Amay be moved toward or from each other, and to thus adjust the barsrelatively to each other a transverse screw, D, is held in a swivel, E,on one of the outer bars, and works through a swivel-nut on the bar attheopposite side, so that accordingly as the screw is turned thebarswill be opened or closed. On the under side these bars are providedwith springs a, at each edge of the said bars A, and more or less innumber, the springs on the edge of one-bar having corresponding springson the adjacent edge of the next bar, forming pairs of springs, whichare adjustable relative to each other by the movement of the bars A,

as above described, so that the shanks or part of the article not to beplated may be introduced between the said springs, as indicated by thecoffin-screw G, Fig. 2, each pair of springs holding its individualarticle as in a clamp.

To the bars A a yoke, H, is attached, at the center of which is a nut,I'. Into this nut the screw L of the hookP is introduced,

having first placed thereon a set-nut, R. This hook is for suspendingthe frame, and is hung upon the pole S, over the bath.

The screw on the hook P'enables the adjustment of the frame to difierentelevations hence, to adjust the frame for plating, the hook is turned inthe nut until that portion of the article to be plated will be entirelysubmerged in the bath, but the frame itself and the clamps will be abovethe surface of the bath; hence no deposit will be made on the part ofthe article which does not require to be plated, or on the frame itself,thereby effecting a great saving of the coating metal.

When the frame has been once adjusted the set-nut R is turned hard downupon the nut I, preventing any accidental disarrange ment of the framerelative to the pole or surface of the bath.

Other holders may be substituted for the bars and clamps to adjust theframe to the particular article to be platedthe yoke or support H, withits fixed nut I, and set-nut R, with a screw-hook whereby the adjustmentis effected, being the essential feature of this invention.

I claim- 1. In a holder or frame for electroplating,

the combination of the fixed nut I, set-nut R,

and screw-hook, substantially as described.

2. The combination, in an electroplatingframe, of the adjustableparallel bars, and

spring hooks or clamps on said bars, the hooks on one bar correspondingto the hooks on the next bar, substantially as described.
